From: Feasibility of a physical activity programme embedded into the daily lives of older adults living in nursing homes: protocol for a randomised controlled pilot feasibility study

Primary research questions
Is the intervention feasible and acceptable to staff and participants?
 • Is the time commitment required for staff to monitor the intervention and participants to partake in the intervention feasible?
 • Are there any environmental barriers to completion of the intervention?
 • Is the content of the intervention acceptable to participants and staff?
 • Do the participants adhere to the intervention and what adherence issues arise?
 • What are the components of usual care for participants allocated to the control group?
Are the outcome measures feasible and acceptable to participants?
 • What is the required time and number of visits required to collect each outcome from participants?
 • Are the outcome measures acceptable to participants?
 • What is the level of missing data within the self-reported outcome measures?
 • What is the feasibility of collecting health economic data (i.e. sources used and time taken)?
